To all whom t may concern.'

Be it known that I, ADOLPH A.. HUNZIKER, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented a certainnew and useful Improvement in Temporary Binders, of which the followingis a specification.

An object of the present invention is t0 provide improvements in theposts and post mountings in a temporary binder, and a specific object ofthe present invention is t0 so construct the posts and their mountingsthat a neater, less costly and stronger binder is obtained. y

My improvements apply especially to that type of temporary binder shownin my Patent No. 605,717, of June 14:, 1898, entitled file and binder,and are fully described in the following specification and shown in thedrawings in which like reference number refer to like parts and inwhich,

Figure 1 is a perspective view of the assembled anchor plate or stripwith the respective pairs of separable posts mounted thereon, showingthe posts of one pair separated. Fig. 2 is an end view of the same withthe parts in section and showing the assembled anchor plate and postsmounted in the binder cover and showing leaves or sheets held by saidposts, parts of the cover and leaves being broken away. Fig. 3 is alongitudinal vertical section on the line III-III, Fig. 2. Fig. 4c is aplan view of a portion of the anchor plate and a pair of posts mountedthereon showing also in plan the clamp for securing said posts to theanchor plate.

Referring now in detail to the drawings, 1 is the anchor plate of myimproved temporary binder to which is secured a clamp 2 by tongues 3which extend through perforations i in plate 1 and are bent fiat fagainst the under surface of said plate.

Clamp 2 has a central raised or arched bearing portion 5 which forms arecess in the under side which receives the bent lower end or lateralextension 6 of a stationary post 7 and is riveted thereto by a rivet 8which passes through the lower end or extension 6. Extension 6 extendsentirely across the clamp 2 and the bearing portion 5 of the clamp 2 isnotched inwardly at 9 at its end to receive the vertical portion ofstationary post 7 and is also notched at 10 to receive a movable post11. The movable post 11 is pivoted at 12, Fig. 2, to the lower end 6 ofthe stationary post 7 Posts 7 and 11 are at their upper end curvedtoward each other' and provided with an interlocking joint, in thedrawings being shown as a recess 13 in the post 7 and a tongue 14 on thepost 11.

The foregoing illustrates the method of mounting a pair of posts on theanchor plate of the temporary binder. Any number of pairs of such postsmay be used in the binder, in the drawings there being shown but twosuch pairs. When the posts are mounted on the anchor plate, the same issecured preferably to one of the cover leaves 15, in a manner, forinstance, as shown in the drawings, wherein oppositely facing grooves 16are formed in leaf 15 which receive the opposite edges of the anchorplate 1 after which the anchor plate 1 and clamps 2 are covered by afinishing layer or lining 17 of suitable material.

18 represents the back of the binder cover substantially equal in depthto the depth of the binder posts and hinged to the leaf 15 of the cover.19 is the opposite leaf of the cover.

What I claim is:

In a temporary binder, an anchor plate, a clamp secured to said plateand having an arched bearing, a stationary post having one end bent toform a lateral extension which extends through said bearing, and amovable post pivoted to the end of said lateral extension, said bearingbeing notched at the ends to receive said binder posts.
